SIP connection direct to CCM

Is it possible to configure a SIP line-side connection directly on CCM 6.x? I've seen the CUBE feature for a SIP trunk, but the SP is providing a SIP line connection (ie they expect a SIP phone on the other end), however - is it possible to achieve this from the CCM?

My customer tells me that with their old Aastra system making these connections was no problem - and now they are quite annoyed that they can't seem to achieve the same with the CCM.

Any help or comments appreciated...

Well after months of trying to get a Cisco solution to work I gave up. I tried multiple direct SIP configurations, CUBE, etc., but to no avail. TAC told me what I was attempting was not supported.

Finally I just placed a trixbox server on a laptop and configured a SIP trunk to the CUCM. The trixbox has SIP trunks out to the SIP service providers. This solution works really well and the customer is extremely happy to have it working! Just wish I did this months ago!
